DIFFERENCE BETWEEN EVAPORATION AND VAPORIZATION EXPLAINED !!

Though the two processes, evaporation and vaporization, sound similar in meaning, there is some difference between vaporization and evaporation. When we closely look at those two processes at molecular level, we can realize that these two processes have distinct features and they are not identical. Both evaporation and vaporization take place in liquids by escaping molecules from the liquid phase to its gas phase, but in two different ways. Vaporization is a surface process whereas the evaporation is a bulk process. In this article, we will discuss the features in each process and compare them in order to find the differences between vaporization and evaporation in terms of how they occur and what are the special features in the process.

What is Vaporization?

Vaporization is a spontaneous process which occurs at the surface of a liquid. It is the conversion of a liquid to its vapor; it is the reverse of the process of condensation. The rate of vaporization increases as the temperature increases.Vaporization depends on the external factors such as wind speed, humidity, temperature and the surface area of the liquid. Vaporization takes place at a faster rate when the external pressure is low. When evaporation takes place, the external environment gets cool down, because heat is absorbed for this process to occur.

What is Evaporation?

Evaporation is a phase transition, where liquid phase changes to its gas phase at its boiling point. Evaporation is independent of the temperature, but it depends on the atmospheric pressure since the boiling point mainly depends on the atmospheric pressure. Different liquids have different boiling points and it depends on the strength of intermolecular forces. When the vapor pressure of a liquid equals to the external pressure upon the liquid, it starts to boil. This is called evaporation and it depends on the atmospheric pressure. 

Summary:

1.Vaporization is a transitional phase of an element or compound from a solid phase or liquid phase to a gas phase while evaporation is a type of vaporization wherein the transition from a liquid phase to a gas phase takes place below the boiling temperature at a given pressure, and it occurs on the surface.

2.Vaporization changes the phase or state of matter from a solid or liquid to a gas while evaporation changes the liquid state of matter into a gas.

3.Vaporization can occur with boiling, sublimation, or evaporation while evaporation can happen with the right amount of heat, humidity, and air movement.
